我在 Ubutu 服务器上有一个项目。我不断收到以下错误

\FatalThrowableError: Call to undefined function bandwidthThrottle\tokenBucket\util\bcsub()
in vendor/bandwidth-throttle/token-bucket/classes/util/TokenConverter.php:80


 public function convertMicrotimeToTokens($microtime)
    {
        $delta = bcsub(microtime(true), $microtime, $this->bcScale); // <--- this line
        return $this->convertSecondsToTokens($delta);
    }

我们使用的包是 bandwidth-throttle/token-bucket，我们使用的是 2.0

我已确保在服务器上的每个 php 版本中都安装了 bcmath

我跑了以下；

sudo apt-get install php7.1-bcmath
sudo apt-get install php7.2-bcmath
sudo apt-get install php7.3-bcmath
sudo apt-get install php7.4-bcmath

sudo service apache2 restart

当我运行“php -r”print_r(get_loaded_extensions());“”时，我得到以下信息，所以我知道它在那里，但我的项目无论如何都会抛出错误

Array

    [0] => Core
    [1] => date
    [2] => libxml
    [3] => openssl
    [4] => pcre
    [5] => zlib
    [6] => filter
    [7] => hash
    [8] => pcntl
    [9] => Reflection
    [10] => SPL
    [11] => session
    [12] => standard
    [13] => sodium
    [14] => mysqlnd
    [15] => PDO

    [42] => sysvmsg
    [43] => sysvsem
    [44] => sysvshm
    [45] => tokenizer
    [46] => xmlreader
    [47] => xmlwriter
    [48] => xsl
    [49] => Zend OPcache
)

我还跑了 print_r(get_loaded_extensions()); 在网络服务器上下文中（如：通过浏览器获取它，而不是在 shell 上）

...
[13] => apache2handler 
[14] => mysqlnd 
[15] => PDO 
[16] => xml 
[17] => bcmath <-------
[18] => calendar 
[19] => ctype 
...

有什么建议吗？

我现在发现设置的php版本是7.2，我知道php.ini在哪里
